How about syncing "Another One Bites the Dust" to videos of U.S. bombing raids in Afghanistan? Or clips of Tom Daschle synced to "You're So Vain" or "Short People" (by Randy Newman). Or "That Don't Impress Me Much" to clips of various world leaders (such as the Ayatollah) making toothless threats?
It opens up a whole new avenue of humorous possibilities, just as the Tourist Guy did.
